A review of freshwater crayfish viruses
Four crayfish viruses have been described since the recent first description of a natural virus infection in freshwater crayfish. There have been additional reports of viruses infecting freshwater crayfish, but these viruses have not been properly described. Experimental or natural infections of freshwater crayfish by viruses important in the aquaculture of other organisms have also been reported. Freshwater crayfish viruses have been tentatively grouped with virus families based predominantly on morphology in thin section transmission electron microscopy. Intranuclear bacilliform viruses (IBV) have emerged as the most important virus group in freshwater crayfish as five intranuclear bacilliform viruses (IBV) infect species in all 3 families of freshwater crayfish on four continents. Crustacean IBVs are currently unclassified viruses. However, those that infect the gut are morphologically similar to penaeid baculoviruses. Other viruses which naturally infect freshwater crayfish have been tentatively assigned to the Parvoviridae and Totiviridae virus families. The current state of knowledge on crayfish viruses will be reviewed, with particular emphasis on the need for caution when translocating crayfish.
